So awhile back I had a lot of problems with stalling and starting, finally bought a new carburetor and it started right up and ran great... Then I went to get a car wash and I went to start it wouldn't stay running unless I kept giving it gas, so got home tried making some carburetor adjustments and it starts fine now runs rough but everytime I come to a stop it dies. Unless I give it constant gas. Also, after the carburetor install I noticed a high pitched whistle when I press on the accelerator maybe vacuum leak I'm Not sure. Are these problems related? Any help would be great. Thanks guys.
